When I click the link in the reset password email, it tells me it expired already.

As is typical with password reset links, it will expire within a short amount of time in order to prevent another person from using the link and resetting your password without your knowledge. There are a couple of reasons the link may expire: 

• The time limit of 4 hours has already passed. Our reset links have a validity of only 4 hours. If more than 4 hours have passed since you received the email, you will have to follow the steps to request your password be reset once again.
• You have requested multiple resets and are not using the most recent one. As soon as you request a second or third reset, the earlier links that were provided expire immediately upon request of the most recent reset. It is recommended to request only one password reset per hour to reduce the possibility of this happening.
